In molecular biology, a reading frame is a way of dividing the sequence of nucleotides in a nucleic acid (DNA or RNA) molecule into a set of consecutive, non-overlapping triplets. Where these triplets equate to amino acids or stop signals during translation, they are called codons. A single strand of a nucleic acid molecule has a phosphoryl end, called the 5′-end, … WebJun 27, 2024 · reading frame A sequence of bases in messenger RNA (or deduced from DNA) that encodes for a polypeptide.

How to determine the most likely reading frame of a DNA sequence?

WebReading frame. In biology, a reading frame is a contiguous and non-overlapping set of three- nucleotide codons in DNA or RNA. There are 3 possible reading frames in a mRNA strand and six in a double stranded DNA molecule due to the two strands from which transcription is possible. This leads to the possibility of overlapping genes and there may ... WebQuick Reference. A sequence of bases in messenger RNA (or deduced from DNA) that encodes for a polypeptide. Since each coding unit (codon) of the genetic code consists of three consecutive bases, the reading frame is established according to precisely where translation starts.
